" AUXILIARY COOLING SYSTEM FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed February 15, 1918. Serial No. 217,366.

To all whom it may concern: Be it known that we, FRANK HINDE and WALTER H. FLEWELL, citizens of the United States, residing at Early, in the county of Sao and State of Iowa, have invented certain new and useful Improvements in Auxiliary Cooling Systems for Internal-Combustion Engines, of which the following is a specification. r

The invention has for an object to enable the incorporation upon internal combustion engines of motor vehicles such as are in familiar use, an auxiliary Water circulation system having a limited amount of radiation, whereby the engine may be maintained at a higher temperature than is possible with the ordinary radiator, being specially intended for use in extremely cold weather. It is an important aim of the invention to enable the incorporation of this auxiliary device without the removal of the ordinary radiator usually mounted upon the front of the vehicle. An additional purpose is to so construct the appliance that it may be readily incorporated upon a vehicle within the hood ordinarily employed to inclose the engine. Another important aim is to improve the structural features of the device, particularly with reference to the connections between a water tank element and the ;water connections of the motor.

Additional objects, advantages and features of invention reside in the construction,

arrangement and combination of parts as here'mafterdescrlbed and shown 1n the drawings, wherem,

Figure 1 1s a front elevational view of'one of the possible embodiments of our invention,

Fig. 2 is a side elevation thereof.

Fig. 3 is a side elevation 'of'an' engine equipped with a modified formof support for the coil, while,

Figs. 4.- to 6 illustrate plan views of blanks of mounting, devices.

. There is illustrated a mot-orlO of a familiar construction, having a water acket portion 11, the upper part of which-is included in a cylinder headcastmg 12, secured by the usual cap screws 13, su tably an inlet 14 at its lower part, and an outlet 15 at its upper forward end, the lnlet being located centrallyof the motor at one side.

An ordinary Water radiator .16 is shown in of the motor.

front of the engine, in its usual relation to the engine. Mounted over the engine there is reservoir 17, the reservoir being suitably shaped at its upper side to avoid abrasion or obstruction of the hood 18, and being carried upon resilient brackets 19 secured upon the upper side of the engine by cervtam of the cap screws by which the head casting 11 is held upon the cylinder casting j The brackets 19. are located one adjacent the forwardend of the reservoir, and one adjacent the rear end, and each is formed integrally of one bar of resilient metal of suitable strength having an upper horizontal portion 20, one end portion being :bent downwardly at right angles thereto, as

at .21, and having a horizontal foot flange 22 formed at its extremity to rest snugly upon the upper side of the head 12. The

opposite end portion of the bracket is bent mwardly beneath the horizontal portion 20,

so as to lie snugly thereunder, and curved downwardly in the form ofan ogee, whereby its extremity may rest upon the top of the head 12, this end-portion being located beneath the portion .20 intermediately of the length of the latter, so that the bracket may be projected considerably beyond one side of the motor, as will be readily understood.

The foot'flange'22 is disposed upon the left side of the head 12 while the opposite end portion 23, isadapted to be adjusted upon the top of the engine at the right handside, or on the-side opposite that; at which the spark plugs are usuallylocated, which in, some cases maybe the'leftside, and it will be readily understood that the brackets may be reversed in suchcases. The reservoir 17 is disposed uponthe'horizontal portions of.the-bracket, and is of a widthless than the length ofthe: portion 20, which extends transverselyof the motor. Engaged over "the receptacle and against each side, there is astrap yoke 25 alined with each bracket,

its extremities being shaped into screw ele-..

ments 26, which are extended through suitableapertures in the portion 20 and the inturned part of the bracket thereadjacent, nuts27 being engaged therewith toclamp the reservoir upon the brackets.

' The-reservoir is. provided with a filler spout 28, having a-filler cap 29 of a familiar form, and is. provided with, an inlet nipple 30 at its forward end, extending horizontally,whileat the rear end ,upon the bottom of the reservoir an outlet nipple 31 is located having a form and direction to be subsequently indicated. The'cylinder head 12 is formed with an outlet connection 15, and a U fitting 33 is provided, having a base flange 34 which may be bolted to the flange 35 of the outlet 15, the opposite end of the fitting extending in alinement with the inlet 30 of the reservoir, so that a hose connection 32 maybe readily formed in the familiar way. A bracket piece 40 is secured by the bolts 41 holding the fitting 33, this bracket pieceqextending laterally beside the engine, andbeing turned forwardly in a vertical plane beside the engine. The forwardly extended part of the'bracket is apertured and receives a; bolt 41 therethrough by which amounting lug 42 of a cooling coil 43 is secured, the lug'42 being formed from a blank of sheet metal of suitable thickness, provided with lateral arms 44 which are bent outwardly to receive parts of the coil therebetween, and are then bent inwardly around respective reaches of the coil, whereby the latter is secured. The coil 43 in the present instance is in substantially the form of the letter W, with the side strokes terminating towardthe rear of the motor, and the A shaped central portion stopping short of the outlet connection 14 of the motor. The

lower arm of the coil, 45, is bowed downwardly and provided with a drain cook 46 at its lowest point. The uppermost arm 46 of thecoil-i. considerably longer than the arm 45, and, the extremities of both of the last mentioned two arms. are extended upward-lyin an arc concentric with the bolt 41, for: purposes to be described. The outlet nipple 31' of the reservoirv 17 is extended in ap-correspending rc, in alinement withthe terminalof the are 46 of the coil, while the outlet fitting47 on the motor has a nipple extension similarly concentric and alined with the terminal of the arm 45 of the coil.

.Hose section (aouplings 48 and 49 respectively are engagedbetween the terminals of the arm 45; and the outlet fitting 47 and the outlet 31 of the reservoir.

In theuse of this appliance, it will become necessary from time to time todisconnect the coil, and it will be seen that by the relation of the terminals of the arms 45 and 46 to the axes of the "bolt 41, connection and disconnection of the hose couplings 48 and d 49 is. greatly facilitated, as'one movement of the ceiljon the bolt 41'as the pivot serves to move the coilterminals in the pr0perdirection for engagement with'the hose, and to permit proper: adjustment of-the hose couplings thereon. and" on the outlet nipple.

' The coupling- 48 being firstengaged, under upwardmevem nt ofthe coil as described, the terminalof the arm 45 will have some distance yet to, moveibefore the hose couling 49 requires to be" adjusted on-the outlet connected, by loosening the bolt 41 and the hose coupling devices after which the terminalsof the arms 45"and "46 may be simultaneously borne downwardly it before explained. The coupling 34 is then loosened and the strap yokes 25 removed from engagement with the brackets 19, which permits removal of the reservoir 17. The cylinder head may then be removed in the usual way, with the bracket 40 and coil attached thereto, if desired, or the coilmay be removed by the removal of the bolt 41. The removal of the usual bolts holding; the cylinder head will release the brackets 19, which may be readily returned to their proper positions when theparts are again assembled.

If preferred, the coil 43 may be provided with the mounting y0ke42" in a position to be secured by the bolts 50 holding the outlet fitting 47 upon the side of the cylinder'cast ing, (see Fig. 3) and the terminals of'the arms 45 46 may then be made concentric with the bolt 50; In such event, incaseit' becomes desirable to connect the motor up with the regular radiator, it is only necessary to loosen the bolt 50 and-thehose couplings 48- and 49 'c'orrespondingto the couplings 48 and 49 before mentioned, whenthe device may be moved piyotally so th'at'its lower arm will swing forwardly and upwardly, clearing the way for the engagement of the usual conduit pipe from the outlet 14 of themotor to the inlet 51- at the lower part of the usual radiator." The coupling 33 maythen be removed and'the ordinarycoupling replacedand hose connections made as ordinarily practised. What is claimed: 1 p 1. A device of the character described comprising a motor having a water jacket provided with inlet and'outlet, a'plufrality of resilient brackets carried'by the motor,
